To calculate the concentration in PPB:
\[ ppb = mg/L \times 1000 \]
Where:
Milligrams per liter (mg/L) is a unit of concentration commonly used in chemistry and water quality measurements. It represents the mass of a substance in milligrams dissolved in one liter of liquid.
Parts per billion (ppb) is another unit of concentration that indicates the number of parts of a substance in a billion parts of the total. It is often used for measuring very low concentrations of pollutants in water, air, or soil.
Let's assume the following value:
Using the formula:
\[ ppb = 0.5 \times 1000 = 500 \text{ ppb} \]
The concentration is 500 ppb.
